    Abstract: The present invention relates to a lithographic printing plate precursor having a good press life with a practical energy amount, which can be on-press developed without passing through a development processing step after recording an image using an infrared laser. The lithographic printing plate precursor comprises a support and an image recording layer, wherein the image recording layer comprises (A) a polymerization initiator, (B) a polymerizable monomer, (C) a binder polymer, and (E) an infrared absorbent and (F) a microcapsule containing a polymerizable monomer in the capsule wall, the image recording layer being imagewise polymerization-curable upon irradiation of actinic ray. The lithographic printing plate precursor is capable of development and printing by loading on a printing press after imagewise exposure and supplying an oily ink and an aqueous component.
